To aZZ whom it may concern.-

Be it known that l, CARL Aucosr J AN son, a subject of the King ofSweden, and a resident of Chicago, in the county of Cool: and State ofIllinois, have invented certain new and useful Improvements inEmulsifiers, of

which the following is a specification.

This invention relates to apparatus for mixing liquids, and isparticularly adapted ject by the device shown in the accompany-- 1 line22 of Fig. 1.

for emulsifying milk and fatty oils in the" manufacture of renovatedbutter or substitutes for butter.

Themain object of this invention is to provide a simple, inexpensive,and eflicient apparatus of this class. I accornphsh this obm drawings,in which- Tigure 1 1s a top plan, partly broken away,

of an emulsifier constructed according to my In the construction shownin the drawings the supporting-frame 4 is in the form of a bowl at itsupper part and has journaled therein a vertically-disposed shaft 5. The

, shaft/5 is adapted to be rotated by mechanwisin in the lower part ofthe supporting-frame 4,,but omitted from the drawin s. on the upper endof the shaft within the bowl 4 is a vessel 6, which is substantiallycylindrical and has an openin 7 in its top of considerably less diametert an that of the side walls." The )GllPl'lfilY of the vessel 6 isprovided with a eavy head 8 to give afiycvheel effect and insure thesteady rotation of the vessel.

' The inner surface of the side walls of the vessel is provided with aplurality of narrow radially-disposedblades 9, which insure that thecontents will rotate with the vessel. The bowl of the supporting-frameis provided with a cover 10, which has a central 0 ening 11, re isteringwith the opening 7 in t e vessel; ll itation of the contents of thevessel during its rotation is accomplished by means of a stirring-arm12, which is' carried by a lever 13, pivotally connected to the cover 10by means of the bolt 14., which is threaded into the cover 10 andprovided with a knurled head. This bolt, also serves as a' clamp forsecuring the lever in the desired angular Mounted position. The arm 12extends throu h the openings 1.1 and 7 and has a vertical y-disposedpart 15 adjacent to the side walls of the vessel 6. This part 15 may beadjusted toward and away from the wall by swinging the handle 13 on itspivotal axis. The part 15 is provided with a series of conical apertures16, having their axes disposed at an angle to the peripheral directionof rotation of the vessel 6. The disposition of these apertures is bestshown. in Fi 3. the part 15, which faces the rotating contents of thevessel 6, is also disposed at an an le to the peripheral direction ofmovement of said particles and serves to guide the same toward The side17 of the apertures 16. The wall 18 of the part 15,

which lies between each a erturo 16v and the adjacent wall of the vesse6, is sharpened at the front edge 19 and is of scalloped or fluted form,so as to provide channels in its face intermediate between the apertures16. Such of the contents of the vessel as pass through the apertures 16are thrown inward out of their normal path, while adjacent particlespass in a direct course through thechannels 20. This action causes athorough agitation of the watery and oily contents and produces anemulsion. The emulsified contents are drawn oii by the curved pipe 21,the nozzle 22 of which faces the peripheral direction of rotation of thecontents of the vessel, and the momentum of said contents causes thesame to be carried out through the pipe 21. The pipe 21 is mounted uponthe cover 10 and is adjustable radially by means of its threadedconnection with a knurled sleeve 23, which is mounted to rotate, but issecured against radial shifting on the cover.

A pair oirthe receiving vessels or funnels 24 and 25 are rigidlyconnected together and removably secured to the cover 10. Each of thesehas a s out 26 extending into the unddie part of t 1e vessel 6 to apoint near the bottom.

In the operation of the device shown the liquids which are to beemulsified are fed into the funnels 24 and 25. The rotation of thevessel 6 causes these to fly outwardly and ac cumulate against the outerwalls of said vessel. The stirrer 12 disturbs the continuous circularrotation of the contents and causes portions thereof to be deflectedinward toward the middle of the vessel 6, while adjacent portionscontinue their circular motion. This peculiar agitation insures themixture of the watery and fatty particles in the form of 'same at .anangle to the adjacent wall ofan emulsion, which 'is'finally drawgh infat the top of the vessel by means of the fiipe'izl and is then, in thecase of butter, ready to be churned and packed.

VVhat I claim as my invention, and desire 'to secure by Letters Patent,is

'frame and extending into said vessel, said stir part a 'acent to theside walls of said vessel f-and sai part having a plurality of aperturesextending through the same at an angle to the adjacent Wal of the vesseland adapted to deflect portions of the contents inwardly awayfrom saidwall against the centrifugal 1:20-

aetion."
